Worth including this part that showed to our face why black panther movie tried so hard to hide the kind of cold bloody murderers the black panther brotherhood is.
All of them felt so deadly like they cant wait to kill anyone over any little thing even their own family!

-Oh, mercy, king. Mercy.
-Every breath you take is mercy from me.
-King!
The world watches.

And that's the reason why, all the nasty stuff take place behind the scenes where the world is not watching.

Here some clues that show the blood thirsty criminals the ones who run wakanda/earth are!(the female bodyguards of the king looked like the blood thirsty reptilian amazons from wonder woman movie and like the red bloody knights/bodyguards of snoke from star wars too! Hell even their dressing and weapons were similar especially in the scene where they were trying to break the necklace of the bad king their weapons looked so identical to those of Snoke's praetorian guards).

-If he touches you again,
I'm going to impale him to this desk.

-Only reason I don't kill
you where you stand
is because I know who you are.

-One more word,
and I will feed you to my children.

-Would you kill me, my love?
-For Wakanda?
Without question!

and many more

Of course they didnt proceed to do those things cause... literally the world watches this movie, like in the V tv series with the reptilians/lunar scum they dont like to be seen in negative light.

See literally all heroes/lunar scum in disguise in all hollywood movies except deadpool lol how they avoid to kill even their worst enemy because the world watches hahaha!

At 0:08 WAIT!... The world watches! HAHAHAHAHAHAHA!
(wow this deadpool movie fooled us all. at 1:11 there's no bullet wound on the head and francis moves his tongue too after hahaha, it really pays off to pay attention to details doesnt it, it saves us from being easily fooled that's for sure.)
